Airworthiness Directive 01-13998
one-timeAirworthiness Directives; Boeing Model 737, 747, and 777 Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737, 747, and 777 series airplanes, that requires replacement of the seat track fittings on all passenger seats with new, improved fittings. The actions specified by this AD are intended to prevent unrestrained movement of the passenger seats during high forward deceleration of the airplane, which could result in injury to the passengers or crew members during an emergency landing.
Which aircraft AD 01-13998 applies to
Whether AD 01-13998 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
